DEVONIAN FAUNAS. a1 
characterizes a conspicuous coral bed. The New Jersey specimens are 
always more or less completely silicified, and have been altered so that 
the mural pores can rarely be detected, even in thin sections. 
CLADOPORA MULTISERIATA Nl. SP. 
Plate XXVI., Figs. 2-3. 
Description.—Corallum consisting of cylindrical branches, which 
occasionally divide. Corallites cylindrical, directed obliquely to the 
axis of the branches, apparently free from septa or tabule, arranged 
in twelve or thirteen vertical series; the apertures in adjacent series 
being more or less irregularly alternate. Because of the obliquity of 
the corallites, their apertures are elliptical, the peripheral borders 
regular, subangular. 
The diameter of the branches is from 2 mm. to 3.5 mm., with six 
or seven corallites occupying a space of 5 mm. longitudinally. 
Remarks.—This species has only been recognized in the upper beds 
of the formation near Hainesville. 
HYDROZOA. 
STROMATOPORA CONCENTRICA Goldf. 
Masses of a Stromatoporoid, which may provisionally be referred to 
Stromatopora concentrica, occur more or less abundantly in the coral 
bed at the base of the Coeymans limestone. They are always more 
or less silicified, so that they are not in a proper condition for study, 
and no correct identification of either the genus or the species can be 
made. The form may always be recognized by the more or less sub- 
globular form of the masses, with their concentric, laminar structure.
